I was able to give Ayane a go in upcoming Wii U game Ninja Gaiden 3: Razor's Edge tonight at a Tecmo Koei press event in Tokyo. Tecmo Koei said that they were only offering a playable demo at their event as what they had to show was too bloody and violent for the Tokyo Game Show floor. After playing the demo, I can easily believe that.
Ayane, the kunoichi, is is a new playable character in this Wii U version, and a bit of a change of pace from series protagonist Ryu Hayabusa. Team Ninja's Fumihiko Yasada, game director, said that the image of this beautiful girl fighting and getting bloody "symbolizes the experience and challenge you will feel in Ninja Gaiden 3: Razor's Edge."
